NOTE-BOOK.

SPECIFICATION forming part Of Letters Patent No. 700,648, dated May 20,1902.

Application filed January 9, 1902. Serial No. 89,075. (No model.)

To all whom, it may concern:

Be it known that I, ABNER-LmwooD HoL- TON, a citizen of the UnitedStates, residing at Norfolk, in the county of Norfolk and State ofVirginia, have made certain new and useful Improvements in Tablets, ofwhich the following is a specification.

My invention is an improvement in tablets in the form of note-books, andespecially in books of such character designed for use by stenographersin taking notes; and the invention consists in certain novelconstructions and combinations of parts, as will be hereinafterdescribed and claimed.

In the drawings, Figure 1 is a perspective view of my note-book as inuse. Fig. 2 is a detail sectional view, the base-plate beingpartiallybroken away. Fig. 3 is a detail per spective view of thebase-plate, showing the latch-plate in unlocked position and one of thebows detached. Fig. 4 is a bottom plan View of the base-plate andlatch-plate, showing the ends of the bows secured by the latchplate.Fig. 5 is a detail perspective view of a portion of the base-plate withone of the fixed posts in place and differing slightlyin constructionfrom the posts shown in Fig. 3. Fig. 6 is a detail perspective view ofone side of one of the bows formed to fit the post shownin Fig. 5; andFig. 7 is a detail bottom plan view, partly broken away, showing asomewhat different form of latch from that shown in Fig. 3.

The note-sheets A may be ruled, as is usual for stenographic use, andare provided with perforations a to receive the fixed posts and thebows. The fixed posts B are mounted on or otherwise suitably secured tothe baseplate O and are made in cross-section in the form of segments ofa circle and for interlocking engagement with the bows D. The posts Bare arranged adjacent to perforations E, formed through the base 0 andthrough which project the ends of the bows D, the latter being providedwith notches cl for engagement by the latch-plate operating beneath theplate 0. In Figs. 1,2, and 3 the bow and posts are formed, as best shownin Fig. 3, the upper ends of the posts B being notched at I) and thebows D being formed with the tenons D to fit along the inner sides ofthe posts B, the shoulders cl at the upper ends of the tenons D beingformed to fit in the notches b in the upper ends of theposts B, thusinterlock ing the bows D and the posts B, as will be understood fromFig. 3. The bows D project at their ends in position for engagement bythe latch-plate F, which slides longitudinally in a dovetail groove inthe under side of the base-plate O and is arranged to enter the notchesd when the parts are in the position shown in full lines, Fig. 4, andhas notches f, which may be adjusted to coincide with the openings E inthe base-plate when it is desired to apply or remove the bows D. Theplate F may be easily adjusted longitudinally in the guide-groove O ofthe plate 0, and its movement's may be limited by a stop F, projectingthrough a slot 0 in the base-plate C, as shown in Fig.3. By using theplate F, I am able to lock both bows by the same latch. "It will beunderstood, however, that independent latches maybe used for each bow,

and where desired the latch may be a pivoted plate, as shown in Fig. 7,in which the plate G is pivoted at G between its ends and may beadjusted at its'opposite ends into and out of engagement with the endsof the bows.

In Fig. 3 the bow is interlocked to the fixed posts by notching theupper ends of the posts and forming-the bows with projections to entersaid notches. This interlocking, however, may be accomplished indifferent ways, such as shown in Figs. 5, and 6, in which the post isgrooved longitudinally at H, and the bow is provided alongside itsnotched tenon with a tongue or rib I to enter the groove H.

In Fig. 1 I illustrate abase-board J, which is as wide asthe base-plateand as long as the note-sheets and is designed for use when it isdesired to furnish a stiff backing for taking dictation standingor'inany place where a desk is not convenient; This baseboard may be ofmetal, wood, or other suitable material and is preferably detachablyconnected with the base-plate O, a convenient means for securing suchend being illustrated in Figs. 1 and 2, wherein the baseboard J isprovided with an undercut groove J, extending across its face andreceiving the base-plate O, which extends at its opposite edgesufficiently beyond the post B to engage in the groove of the base-boardJ. The baseplate can be conveniently removed from the- ICO groove in thebase-board and turned end for end, this being especially desirable inreversing the base-plate when the stenographer has written through thebook on one side of the sheets and desires to readjust the book to thebase-board so the other sides of the sheets of the book may be writtenupon.

It will be noticed the fixed posts are important, as they hold thenote-sheets together when the bows are removed as well as when the bowsare locked to the base-plate, and when the bows are locked to thebase-plate the posts B rendering the bows more substantial and improvingtheir connection with the base-plate, the posts being immovable and thebows being interlocked with the posts as Well as being latched inconnection with the base-plate. b in the post B are made somewhat in theform of a saw-tooth and being entered by the projections d prevent anydisplacement of the bows when the latter are secured by the latchdevices before described. Furthermore, the form in cross-section of thetenons (Z' and the posts B is half-round, and when fitted together theyform cylindrical posts, fitting the openings at in the note-sheets. Thiscylinder is larger than the diameter of the bow-rod at the crown of thebowsin order to facilitate the adjustment of the note-sheets from sideto side of the bows, this being effected by making the bows with theircrown portions reduced in thickness.

As shown in Figs. 1, 2, 3, at, and 5, the opposite edges of thebase-plate G are beveled or sloped off to an edge, this being desirableto avoid any abrupt bending of the note-sheets where theyoverlie theedges of the base-plate.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The improvement in note-books herein described, comprising thebase-plate sloped or beveled off at its opposite edges, provided withopenings through which the ends of the bows may be passed and with fixedposts adjacent to said openings, the bows fitting alongside said fiXedposts, and devices for securing the bows in connection with thebase-plate, substantially as set forth.

2. In a device, substantially as described, the combination with thebase-plate, of the half-round posts thereon, the bows having half-roundtenons lapping alongside the said posts, and means for securing thebows, substantially as set forth.

3. The combination with the base-plate,aud the posts thereon, of thebows interlocking with the posts, and devices for securing the bows tothe base-plate, substantially as set forth.

It will also be noticed the notches 4. The combination with thebase-plate hav ing openings through which the ends of the bows mayproject, the bows projecting at their ends through said openings andlatch devices for securing the bows to the base-plate, substantially asset forth. a

5. The combination with the base-plate having openings for the ends ofthe bows, and the posts adjacent to said openings, of the bows lappingalongside the posts and projecting through the openings in thebase-plate, and latch devices beneath the base-plate for se-' curing thebows, substantially as set forth.

6. The combination with a base-plate having openings for the ends of thebow and posts adjacent to said openings, the bow fitting alongside andinterlocking with the posts and projecting through the openings in thebaseplate, and the latch-plate beneath the baseplate and' movable intoand out of engagement with the bow, substantially as set forth.

7. The combination with the base-plate and the posts thereon, andnotched in their upper ends, of the bow provided at its ends with tenonsfitting alongside the posts and at the upper ends of said tenons withshoulders having projections entering the notches of the posts, andmeans for securing the bow, substantially as set forth.

8. The combination of the base-plate provided with openings for the endsof the how, the bow projecting at its ends through said opening, and theslide-plate beneath the baseplate and arranged to secure the bow,substantially as set forth.

9. The combination of the base-plate provided in its under side with agroove, and having openings for the ends of the bow, the bow projectingat its ends through said openings and the latch-plate operating in thegroove in the under side of the base-plate and movable into and out ofengagement with the bow, substantially as set forth.

10. The combination with the base-plate provided with openings for thebow and adjacent thereto with posts, the bow fitting at its endsalongside said posts and projecting through the openings in thebase-plate, and the latch beneath the base-plate for securing the bow,substantially as set forth.

11. In a note-book, the combination of the base-board, provided with atransverse undercut groove, and the base-plate fitted to said groove andmovable into and out of the same and provided with bows arrangedtransversely the length of the base-plate for securin g the'note-sheets,substantially as set forth.
